Pure hear-say, but I believe that the "out-of-the-box" kernel doesn't support setting the refresh rate at boot time. All I know is that in one of the love-sources threads on the forums, a person asked about including a patch to have refresh rate selection supported - BUT the selection would be hard coded in the kernel. Check the forums for more information and try googling around for the patch I'm talking about - or possibly a better one! Jason -- [EMAIL PROTECTED] mailing list
